invalid bound statement (not found)

按字面翻譯是invalid bound statement (not found)，指的是找不到Mapper文件
確保你的項目存在相應的Mapper文件後，在mybatis-config.xml中更改設置，將XXXMapper.xml添加進…中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <!-- 延遲加載、懶加載，作用於屬性和對象域上面 -->
        <setting name="lazyLoadingEnabled" value="true" />
        <!-- 是否立即初始化屬性或者對象域 -->
        <setting name="aggressiveLazyLoading" value="false" />
    </settings>
    <mappers>
        <mapper resource="XxxxMapper.xml"/> 
    </mappers>
</configuration>
